Yes Ian, thanks for that. All very well for the UK et al ... but I wonder how much "conventional x-ray" gear continues to soldier on out in (the rest of) the World. It would be nice see survey results (or even feedback from members of this forum).
Lastly (and by the way), I remembered later that my list of "operator errors" (especially those leading to unnecessarily high patient doses) should have included "poor collimation". Indeed, in my experience this was the most common example of (what I would call) sloppy practice by radiographers - hopefully not the case in the UK, though.
But we need a new thread (and I wonder why we don't seem to have touched on this stuff before).
